Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).

The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

Dexter Axles

Dexter axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. The result of this underslung design is a trailer that rides a bit lower for quick and easy loading and unloading.

Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

I inherited an aluminum trailer that ended up needing a complete overhaul and etrailer was the best resource I could have found. After researching extensively to find out what I needed and watching their videos on how to do it I ended up ordering an EZ-lube axle, galvanized hubs, springs and a hanger kit (in other words everything from the frame down). Everything shipped quickly and arrived in great shape. All the parts worked perfectly and I couldn't be happier! 316656

- T20BTR-EZ-7258

Bought this for my boat trailer. Great looking axle took all the measurements and it looked like it would fit. When I put my hubs on it they were about one inch short. So being short there are no threads to tighten the nut against the bearing. So now I need to order there hubs. This should be mentioned when you order the axle. Or give the hub over all length. 313851

The axel is working great with no problems.

Axle arrive in good condition. Went together like it should. Very happy with the product 281113

- T20BTR-EZ-7258

1 yr later, axle and bearing set is working well. I decided to replace the axle under my trailer rather than the whole trailer. I like the pre-bend in the tube for keeping tires balanced under load as well as the basic finish rather than bare steel. Purchase price made it even better after shopping around a bit. 250261

Doing well, as you know, the axle gets used only when the trailer does so it sits a lot. But I do enjoy that it has the pre bend to it so when loaded up it tracks true and the tire wear is even.

- T20BTR-EZ-7258

Shipped fast. Product seems strong. I do have a problem (not etrailer's fault), the axle I replaced didn't have a raised leave spring mount as this one does. That extra inch put my tires into the fenders (literally) :( will have to cut fenders off and probably end up getting another axle maybe one longer so I can have boat ride between fenders instead of over them. 217938

The right part showed up on time. Thank you etrailer.com! 205662


Ask the Experts about this Dexter Axle Trailer Axles

  • Can the Spring Seats On a Dexter 2,200 Lb Axle Be Moved and Re-Welded
    Yes, you can move the spring seats to 53-1/2" apart on the Dexter 2,200 Lb Trailer Axle part # T20BTR-EZ-7258, part # 20440I-EZ-72, or part # 20545I-EZ-72-10. This is pretty common practice as manufactures just place the spring seats in a common spot but the customers can move them as needed. That said, you will likely destroy the old ones getting them off so I also recommend getting the Axle Spring Seat part # TRSS175 (2).

  • Do EZ Lube Spindles Keep Water Out When Submerged
    The EZ-Lube portion of the Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 will keep water out so long as they are greased properly and you use the Dexter Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles # 8-258-5UC1-EZ which does have an EZ-Lube grease cap. This will create a seal that does not allow water in when you submerge your axles. To add grease I highly recommend the LubriMatic Mini Grease Gun Kit with Marine Corrosion Control and Trailer Bearing...

    We have a 2,000 lb axle that has an overall length of 72 inches from hub face to hub face and has a spring center dimension of 58 inches like you need, part # T20BTR-EZ-7258. Check out the review video I attached for more info. We don't have a 3,500 lb axle that has those dimensions. 3,500 lbs is quite a bit of capacity for a 5 by 8 trailer, you might be able to get by with the 2k axle part # T20BTR-EZ-7258.

  • Can Trailer Axle be Replaced With 1 Larger Hub-Face Measurement
    The Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 should work great for your application! The only time that having your hub-face sit out an extra inch would be a problem is if that made your trailer tires touch fenders that you might have on the trailer. If your trailer doesn't have any fenders then you won't have any problems going this route! Please note that if you only have 1 axle this is alright. If you have more than one axle then you'd need to swap out...

  • Axle Capacity of 1-1/2 Inch Square Axle.
    The only way to know for sure the capacity of your axle is based on the information from the manufacturer when the axle is new. Typically, 1-1/2 inch square axels have a capacity somewhere between 1,000 - 2,000 pounds. Sometimes the spindle and hub can also help point us in the direction of finding axle capacity, but even then it is still an approximation since it is impossible to tell if they are the same size as what came on the axle. The bearing number your provided does not match...

  • Can Hubs from Old Axle Be Used With Dexter # T20BTR-EZ-7258 Replacement Trailer Axle
    If your existing hub assemblies use the # L44649 inner and outer wheel bearing, hubs and races are still in good condition, you can reuse them. I'd recommend replacing the bearings and # L44610 races. I wouldn't recommend trying to bend the axle back into place. When the axle was bent, the structural integrity of the metal might have been compromised to an unknown degree. Be safe, replace the axle. The axle has a hub face to hub face dimension of 72 inches and a spring center to spring...

  • Straight Trailer Axles for a 2 Horse Trailer with 3,600 Pounds Gross Trailer Weight
    With the trailer weighing 1,600 pounds and 2 horses at 1,000 pounds each that would total 3,600 pounds which is over the capacity of both a single 2,200 pound axle and a single 3,500 pound axle. But if you have 2 axles then using 2 of the 2,200 pound axles, # T20BTR-EZ-7258, will be more than enough capacity. I have linked a video review of this axle for you.

  • Hub Recommendation for Dexter Trailer Axle part # T20BTR-EZ-7258
    The Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 that you referenced has a BTR spindle on it that takes a hub with an inner and outer bearing of L44649. This would not work with your hubs because they have inner bearing of L68149 and an outer bearing of L44649. To use the axle you referenced you would need to go with the Trailer Hub Assembly # 8-258-5UC1 instead. At 72 inches in length there are no axles we carry that would fit the hubs you have.

We do not have any 4x100 bolt pattern hubs available at all, as this isn't a very common pattern anymore.

For an idler hub you would want the part # 8-258-5UC1-EZ. Or if you want a brake drum you would want the part # 8-257-5UC3-EZ. Both of these hubs will fit the trailer axle and have the 5 on 4-1/2 inch bolt pattern you are looking for.

  • Key Dimensions for Selecting Replacement 2200-Lb Trailer Axle
    The key dimensions to keep in mind as you select a replacement axle are the hub-face-to-hub-face dimension and the spring seat spacing. Axle # T20BTR-EZ-7258 is rated for 2200-lbs and has a 72-inch hub-face (HF) dimension and a 58-inch spring seat dimension as shown in the diagram I linked for you. Overall axle length will of course be a few inches greater than the HF spacing. The E-Z Lube spindle diameter is 1-1/16-inch. We have no axles with 72-1/2-inch hub face spacing.

  • Can Replacement Trailer Axle with Smaller Diameter be Used on a Boat Trailer
    If the axle is bent up in the middle then that is normal. Trailer axles have a bow in them so that when weight is placed on the trailer it flattens out. That is part of what gives an axle its capacity. If there is not enough weight on the axle then the tires will remain toe in at the bottoms and you will get tread wear just on the outsides of the tread. If the axle is bent in some other way then replacing the axle is a good idea. The diameter difference means that you would likely have...

  • 72 inch Long Trailer Axle Recommendation with 2,200 lb Capacity that can Fit 14 inch Wheels
    The difference is the mounting flange on the hubs. Axles that have larger mounting flanges like the part # 20545I-EZ-72-15 can fit the larger wheels, whereas the # 20545I-EZ-72-10 has a small flange that doesn't match up to the bigger wheels. What you would want to do is go with the axle part # T20BTR-EZ-7258 that does not have hubs with it and then use the hubs # 8-258-50UC1-EZ that has the larger mounting flange on it and will give you the 2,200 lbs capacity you want in the correct size.
